1 and 2, a floor brush 100 provided by a specific embodiment of the present invention includes a floor brush body 120 and a roller brush body 130 detachably mounted on the floor brush body 120.

In this way, the roller brush body 130 can be detached from the floor brush body 120 to clean the debris on the roller brush body 130 and improve the cleaning efficiency of the floor brush 100.

2 to 4, this embodiment preferably, the roller brush body 130 includes a first part 131 and a second part 132 connected to each other, the second part 132 moves relative to the first part 131, so that the roller brush body 130 and The floor brush body 120 is detachably installed.

Preferably, in this embodiment, the first member 131 is the main body 133 of the roller brush body 130, and the second member 132 is an end cover 134 provided at one end of the main body 133.

The main body 133 of the roller brush body 130 usually has fluff or flocking to improve the cleaning efficiency. As shown in FIG. 1, the main body 133 is covered with fluff.

The second component 132 moves axially and circumferentially relative to the first component 131, so that the roller brush body 130 and the floor brush body 120 can be detachably installed, which is convenient and quick. Here, the axial movement and the circumferential movement can occur simultaneously. It can have a sequence, that is, the circumferential movement can occur simultaneously with the axial movement. At this time, the circumferential movement occurs passively (as shown in Figure 5 to Figure 12) or actively (such as manual rotation by the user, the structure can be relatively A simple U-shape) can be used. Of course, the circumferential movement can also be performed after the axial movement is completed. Here, the simultaneous or sequential movement is not limited.

Preferably, in this embodiment, an elastic member 140 is provided between the first member 131 and the second member 132.

During installation, pressing the second member 132 against the force of the elastic member 140 makes the second member 132 move axially and circumferentially with respect to the first member 131, and loosen the second member 132. The second member 132 acts on the elastic member 140 Move down to the installation position.

When disassembling, pressing the second member 132 against the force of the elastic member 140 makes the second member 132 move axially and circumferentially relative to the first member 131, and loosen the second member 132. The second member 132 acts on the elastic member 140. Move down to the disassembly position.

The elastic member 140 assists the relative movement between the second component 132 and the first component 131, and the structure is simple and reasonable. Especially, when the roller brush body 130 is in the installation position, the elastic member 140 exerts a force away from the first member 131 on the second member 132, which can keep the roller brush body 130 in the installation position reliably, and the use of the floor brush 100 is more stable. reliable.

As mentioned above, the second part 132 moves axially and circumferentially relative to the first part 131. The roller brush body 130 and the floor brush body 120 are detachably connected.

Specifically, referring to Figures 2, 5 and 6, a guide mechanism is provided between the second component 132 and the floor brush body 120. The guide mechanism includes a guide 142 provided on the second component 132 and a guide mechanism provided on the floor brush body. The guide groove 144 on the 120 includes an open port 146, a fixed position 148 closed at the distal end, and a groove body 150 extending between the port 146 and the fixed position 148. The port 146 and the fixed position 148 are spaced a certain distance in the circumferential direction. The groove 150 extends a certain distance in the axial direction.

The guide groove 144 can define the movement path of the guide 142, so that the guide 142 moves according to a desired path, so that the second component 132 moves in a desired movement mode relative to the first component 131 to complete the disassembly and assembly of the roller brush body 130.

The open port 146 can make the disassembly and assembly of the roller brush body 130 more convenient. When installing, the guide 142 enters from the open port 146 to start to install the roller brush body 130 to the floor brush body 120; when disassembling, the guide 142 exits from the open port 146 to ensure that the roller brush body 130 is removed from the floor brush body 120. Take off, that is, during the disassembly process, the guide 142 moves to the open port 146, and the second part 132 is located at the disassembly position.

Since the guide 142 moves in the guide groove 144, the fixed position 148 is a part of the guide groove 144, and therefore, the fixed position 148 cannot be completely closed. The distal end of the fixed position 148 is closed, which means that the fixed position 148 is closed at the end of the second part 132 away from the first part 131. The fixed position 148 with the closed distal end can make the second part 132 away from the first part 131. The position of is fixed, so that the roller brush body 130 is fixed relative to the brush body 120. That is, during the installation process, the guide 142 abuts the fixing position 148, and the second component 132 is located at the installation position.

The port 146 and the fixing position 148 are spaced at a certain distance in the circumferential direction, so that the port 146 and the fixing position 148 are staggered, which can prevent the guide 142 from accidentally slipping out of the port 146 and ensure the reliable installation of the roller brush body 130. The port 146 and the fixing position 148 are spaced at a certain distance in the circumferential direction, so that the guide 142 generates a circumferential displacement when moving in the guide groove 144; the groove body 150 extends a certain distance in the axial direction. When the guide 142 moves in the guide groove 144, an axial displacement is generated. Therefore, when the guide 142 moves in the guide groove 144, the axial and circumferential displacements are generated simultaneously, so that the second part 132 moves relative to the first part 131 to generate the axial and circumferential displacements at the same time, so that the roller brush body 130 is reliable. The disassembly and assembly.

Therefore, when the guide 142 moves from the open port 146 to the fixed position 148 in the guide groove 144, the roller brush body 130 is located at the installation position, and the roller brush body 130 is installed on the floor brush body 120. When the guide 142 moves from the fixed position 148 to the open port 146 in the guide groove 144, the roller brush body 130 is located at the disassembly position and can be removed from the floor brush body 120.

In this embodiment, the guide groove 144 includes an installation section 152 and a disassembly section 154 that are sequentially connected. The guide groove 144 extending from the open port 146 to the fixed position 148 is the installation section 152, and extends from the fixed position 148 to the open position. The guide groove 144 between the ports 146 is a disassembly section 154.

Preferably, in this embodiment, although both ends of the installation section 152 and the removal section 154 are the same, they are both an open port 146 and a fixed position 148, but the installation section 152 and the removal section 154 are two different paths. The installation section 152 and the disassembly section 154 are separated by a partition 155.

Therefore, the installation section 152 and the disassembly section 154 can be designed separately, and misoperation can also be avoided.

Preferably, in this embodiment, the installation section 152 and the disassembly section 154 both include a guide section 156A/156B, a transition section 158A/158B, and a terminal section 160A/160B that are sequentially connected.

In other words, the installation section 152 includes an installation guide section 156A, an installation transition section 158A, and an installation end section 160A that are sequentially connected. The disassembly section 154 includes a disassembly guide section 156B, a disassembly transition section 158B, and a disassembly end section 160B that are sequentially connected.

Preferably, in this embodiment, an elastic member 140 is provided between the first component 131 and the second component 132, and the guide member 142 overcomes the force of the elastic member 140 to move from the guide section 156A/156B to the transition section 158A/158B, and the guide member 142 The end section 160A/160B is moved from the transition section 158A/158B under the action of the elastic member 140.

Specifically, during installation, the operator overcomes the force of the elastic member 140 to push the second component 132, thereby pushing the guide 142 into the installation guide section 156A from the open port 146 and move in the installation guide section 156A. When the guide 142 moves from The installation guide section 156A moves to the installation transition section 158A. The operator knows that the operation is in place. The operator can loosen the second component 132. The guide 142 moves from the installation transition section 158A to the installation end section 160A under the action of the elastic member 140. Then, it moves under the guidance of the installation end section 160A until it abuts against the fixed position 148, and the roller brush body 130 is installed in place.

When disassembling, the operator overcomes the force of the elastic member 140 to push the second component 132, thereby pushing the guide 142 from the fixed position 148 into the disassembly guide section 156B and move within the disassembly guide section 156B. When the guide member 142 moves from the disassembly guide section 156B Move to the disassembly transition section 158B, the operator knows that the operation is in place, the operator loosens the second part 132, the guide 142 moves from the transition section 158B to the disassembly end section 160B under the action of the elastic member 140, and then at the disassembly end section 160B The roller brush body 130 can be detached from the floor brush body 120 by moving under the guidance of the brush until the opening port 146 is reached.

In this embodiment, combined with the force of the operator and the force of the elastic member 140, the installation section 152 and the disassembly section 154 are rationally designed to make the disassembly and assembly of the roller brush body 130 very convenient.

Preferably, the guide section 156A/156B includes an angled first section 171 and a second section 172, the transition section 158A/158B is connected to the second section 172, and the transition section 158A/158B and the first section 171 Stagger a certain distance in the circumferential direction.

Therefore, when the operator loosens the second component 132, when the guide 142 moves under the action of the elastic member 140, the transition section 158A/158B is not directly connected with the first section 171, and the transition section 158A/158B is connected to the first section 171. The section 171 is staggered by a certain distance in the circumferential direction to prevent the guide 142 from returning to the guide section 156A/156B from the transition section 158A/158B, and the guide 142 can only go from the transition section 158A/158B to the end section 160A/160B, thereby ensuring Reliable disassembly and assembly of the roller brush body 130. In addition, the guiding design of the second section 172 allows the operator to press the second part 132 so that the guide 142 can reach the transition section 158A/158B smoothly, without additional rotation, and the operation is simpler and more convenient.

Preferably, in this embodiment, the extension lines of the guide section 156A/156B and the transition section 158A/158B are different.

When the operator presses the second part 132 and the guide 142 moves in the guide groove 144, when the operator feels that the shape of the guide groove 144 abutted by the guide 142 has changed, the guide 142 has entered a different linear shape. For the transition section 158A/158B, the operator can judge that the operation is in place, the operator can release the hand, and the roller brush body 130 can be disassembled and assembled under the action of the elastic member 140. Therefore, in this embodiment, the guide section 156A/156B and the transition section 158A/158B with different extension lines can be designed to help the operator determine whether the operation is in place.

Preferably, the extension line shape of the transition section 158A/158B matches the extension line shape of the cross section of the guide 142 in this embodiment. This can make the guide 142 fit the transition section 158A/158B well. When the operator perceives this fit, the operator can accurately judge that the operation is in place, and the design is very reasonable.

Specifically, the main body 133 of the guide 142 is cylindrical, and the transition section 158A/158B extends in an arc, so that the guide 142 fits well with the transition section 158A/158B. Those skilled in the art can imagine that the guide The shape of the cross section of 142 and the transition section 158A/158B can be designed according to needs, and any solution that is the same or similar to the embodiment is covered by the protection scope of the present invention.

Preferably, in this embodiment, the number of guide members 142 is several, and the plurality of guide members 142 are evenly distributed in the circumferential direction of the second member 132. The number of guide grooves 144 and the number of guide members 142 are the same and matched one by one.

Specifically, in this embodiment, there are three guide members 142, and the end covers 134 of the three guide members 142 are evenly spaced in the circumferential direction. Correspondingly, the three guide grooves 144 are on the floor brush body 120, specifically on the inner wall of the receiving groove of the floor brush body 120 for receiving the roller brush body 130, evenly spaced circumferentially. This can make the rolling brush body 130 and the floor brush body 120 bear more uniform force, and the installation is more reliable.

Those skilled in the art can imagine that the number of guides 142 and guide grooves 144 can be designed according to needs, and does not constitute a limitation to the protection scope of the present invention. Any solution that is the same or similar to the embodiment is covered by the protection scope of the present invention. Inside.

The following is a more complete description of the installation process of the roller brush body 130.

When installing, please refer to Figure 7. Adjust the angle of the brush body 130 first, so that the three guides 142 on the end cover 134 of the brush body 130 are aligned with the open ports 146 of the three guide grooves 144 on the floor brush body 120 .

8 to 10, the operator overcomes the force of the elastic member 140 to apply force to the end cover 134 in the direction close to the main body 133 of the roller brush body 130, so that the guide member 142 is installed and guided in the guide groove 144 sequentially. The first section 171 and the second section 172 of section 156A move. When the guide 142 moves to fit the installation transition section 158A, the operator can perceive that its operation is in place. The operator releases the hand, and the end cap 134 is on the elastic member. Under the action of 140, away from the main body 133 of the roller brush body 130, the guide 142 moves from the installation transition section 158A to the installation end section 160A, and finally abuts at the fixed position 148.

At this time, referring to FIG. 11, the rolling brush body 130 is reliably installed on the floor brush body 120.

When the guide 142 moves from the open port 146 to the installation transition section 158A, the end cap 134 is close to the body, and the axial length of the entire brush body 130 is shortened; when the guide 142 moves from the installation transition section 158A to the fixed position 148, the end cap 134 is far away from the body, and the axial length of the entire brush body 130 becomes longer. Therefore, during the installation process, the axial length of the roller brush body 130 may change. At the same time, since the open port 146 and the fixed position 148 are spaced at a certain distance in the circumferential direction, the circumferential angle of the roller brush body 130 will also change during the installation process.

The disassembly process of the roller brush body 130 will be described more completely below.

When disassembling, please refer to Figures 10 and 12, the operator overcomes the force of the elastic member 140 to apply force to the end cover 134 in the direction close to the main body 133 of the roller brush body 130, so that the guide member 142 runs along the guide groove 144 sequentially When the first section 171 and the second section 172 of the disassembly guide section 156B move, and the guide 142 moves to fit the disassembly transition section 158B, the operator can perceive that its operation is in place. The operator releases the hand and the end cover 134 is in place. The elastic member 140 moves away from the main body 133 of the roller brush body 130, and the guide member 142 moves from the disassembly transition section 158B to the disassembly end section 160B, and finally returns to the state shown in FIGS. 7 and 9, the guide member 142 reaches the open Port 146, the roller brush body 130 can be removed from the floor brush body 120.

When the guide 142 moves from the fixed position 148 to the disassembly transition section 158B, the end cap 134 is close to the body, and the axial length of the entire brush body 130 is shortened; when the guide 142 moves from the disassembly transition section 158B to the open port 146, the end cap 134 is far away from the body, and the axial length of the entire brush body 130 becomes longer. Therefore, during the disassembly process, the axial length of the roller brush body 130 will change. At the same time, since the fixed position 148 and the open port 146 are spaced a certain distance in the circumferential direction, the circumferential angle of the roller brush body 130 will also change during the disassembly process.

In summary, in the present embodiment, during the disassembly and assembly process of the roller brush body 130, the end cap 134 as the second part 132 moves axially and circumferentially relative to the main body 133 as the first part 131, resulting in axial displacement and Circumferential displacement. The axial displacement provides a moving path for the installation and disassembly of the roller brush body 130, while the circumferential displacement can prevent the roller brush body 130 from accidentally falling off the main body 133. The structure design is very reasonable and the operation is very simple.

This embodiment also provides a vacuum cleaner which is provided with the above-mentioned floor brush 100. Since the rolling brush body 130 of the floor brush 100 is easy to disassemble and assemble, the vacuum cleaner of this embodiment is also more convenient to use, and will not be repeated.
